Finding relatives

I am John Larson from Louisville, Kentucky USA and plan to visit Norway in July 2019. My great grandfather was Bastian Larson born in Fjelberg on 3/26/1/824 and my greatgrandmother was Anna Nordhuus born in Fjelberg on 9/21/1828. They immigrated to USA in 1857.I believe that Basstian's father was Lars Eide. I am trying to find relatives, [email hidden]
